Battery gain w/ HSPA+ - Xperia Z3 Compact Q&A, Help & Troubleshooting

I get really good hspa+ speeds where i live. Good enough that im considering turning off 4g and going with just hspa. Ive read that battery is hit hard by lte use. So my question is how much battery does lte use over hspa in general?

Hspa+ is a form of 4G, so on Tmob USA when you're running on HSPA+ a 4G icon gets displayed.

Yeah kinda sorta i know. What i meant was, i have the option to use 4g or hspa+ on my phone. There is no "lte" option. I didnt bother with the US firmware.

HSPA+ isn't 4G. Actually, LTE also isn't 4G because it isn't fully IMT-Advanced compliant and doesn't meet the requirements (LTE-Advanced does).

My understanding, however, is on a UK firmware, such as I have LTE shows up as 4G. When you switch over to US firmware, the LTE icon actually shows up. Speeds are the exact same from understanding as well.

Yep, it's shown as 4G because it's already being marketed as such, LTE-Advanced (which meets the bandwidth requirement) only requires a base station software upgrade. Simply showing LTE like some firmwares do is more correct though. However, HSPA+ should never show 4G but H+.

I use 2g and switch to 4g when I want to use the Internet.. Battery has lasted 3 days so far 9% left lol no stamina modes either
Sent from my D5803 using XDA Free mobile app

I'm not using 4g and i switched between 3g and 2g (when i wasn't using the phone) and the result was really good. Played some 2d games and watched 45mins of youtube videos.
As you can see i was on the Phone very long today, Screen was around 20-30% brightness. Used some parts of Stamina Mode (don't know their english names but i guess: Advanced Stand-By Mode and Advanced Usage, i didn't use Stamina-Clock or "Ultra Stamina"). The runtime is comparable to my old phone that featured a 3100mAh Battery and a 4.3" screen.

So I did my test. Used only HSPA+ on Thursday, LTE on Friday. No wifi at all. Went to work, used phone normally and as close to the same as possible. I'll post screenshots and more details tomorrow, but long story short... after 22 hours on HSPA+ I had 61% battery remaining. After 22 hours and change on LTE I had 60% battery remaining. No real difference.

I'm on z1c but I've seen the same as you - no real difference in battery life between H+ and LTE.
Sent from my D5503

Could you guys repeat the test with actively using both connections?
You won't see a difference in stand by because both network modes offer power save modes. The biggest difference is while using them..
If you switch to 2g (and turn off Internet) you should still get a better result as the apps won't be able to use the connection and incoming calls / text messages should take less energy as in 3g/4g mode..

When I say I used LTE, what I mean is I had LTE enabled, and it was primarily used, but on my drive to work I go through a HSPA only territory. So for the LTE day, LTE and HSPA were both on. And this turning off internet thing is called Stamina Mode.

Alrighty, here is my HSPA+ vs LTE battery comparison extravaganza!! I tried to use the phone for the same amount of time, the same way, using roughly same amount of data, everything the same, both days. I took my phone off the charger at roughly 10pm both nights (I wanted the long cell connection overnight so I wouldn't have to rush to charge my phone before work in the morning). The TL;DR version is that there was no difference between H+ and LTE. For screenshot comparison of use between the two days, keep reading.
Phone taken off the charger at roughly 10pm, then left to sit there until roughly 6am the next morning.
HSPA+ (left)..................................................................................LTE (right)
Note that the only real difference is in signal strength.
OK, now on to the end of day numbers.
HSPA+ (left)..................................................................................LTE (right)
Slightly less SoT on the LTE day, but that is made up for by the added Pocket Casts use. Overall, no real difference except for signal strength. I'm just gonna leave my phone on LTE.

[Q] 4g LTE

I live about 55 miles outside Chicago and I am getting 2 bars of LTE, should I shut that off? I get full bars of 3g, we are not supposed to have LTE here yet.

If you have it and it doesn't constantly cycle and it works, leave it on. You are not going to get charged extra for it.

Thanks, I am just curious if its worth keeping lower signal over full on 3g?
Not sure if the bars have anything to do with data, I was told it was only for cell service. I could be wrong.

U will save your battery a little on 3G, but if you have 4G then use it. It is ten times faster and once you use it, slower 3G speeds will start to annoy you.

If your signal is too low, it will switch out. You can play a little and see if the weak signal slows your data. Go to speakeasy.com and test you speeds. That will tell you how fast the data is moving up and down.

i have senn 10mb/s down speeds with 1 bar of lte. if you are getting 2 bars you should be good.
I think idefiler6 was dead on.... the bars don't have anything to do with data. The bars only represent the voice. The 4g/3g data connections that are displayed are in addition to the voice signal that is represented by the bars.

[POLL] Are you using 3g or 4g?

This thread is simply voting which data you use and why.
I personally am using 3G (HSPA+ 21) even though I could use 4G (I live in Canada), mainly because of the poor battery like I'm experiencing with this device if used on 4G.
So what are you using? And why?
Using 3G+ (42) because the 4G frequency in Australia doesn't work with the N4, or most phones unless a special model comes out like the 4G version of the S3
Just plain ol' 21/42 MBps H+

3G, no choice, if 4G was an option I'd probably give it a shot but if I noticed extreme battery drain I would go back to 3G as well.
Edge
i live in canada too, but i did several tests, using 4g makes the voice call quality really bad. so i stick with 3g now
I use both... I get pretty decent speed on DC-HSPA about 20mbps down easy... I use lte mainly so i can stream youtube in hd instead of hq!
Sent from my iPhone 5
HSDPA. 1 operator is just beginning to roll out 4G in the major cities here in Belgium, so no choice
And I don't think the LTE chip works here anyway.
I used Edge at work. it streams better for me. Always has. Since iphone 3g. I think its the building I work in. Soon as I leave it, H+ works like it should.
At home I use Wireless and 4g
Soooooo I'm not the only one who is preferring 3G over 4G? Yay lol
I would barf in my mouth before I use 3g.

Faux G aka HSPA+ (21.1 and 14.4) w/EB here as well.
My Provider has just HSPA+ 15 but I mostly hav HSPA+ 10. But that's no problem at all, because I'm used to it. At home (on Computer) I get just about 7 so I'm totally happy.
3G is broken... Once this thing connects top umts or hspa 10 there's no data transmission until it finds hspa+15 again...

3g in Canada. 4g decimates my battery, which is already kind of disappointing personally.

A mix of EDGE, 21, and 42 depending on where I am during my day.

GPRS/EDGE by preference, no point wasting battery power attempting to connect to crappy 3G signal!
3G for me. I've tried 4G and while I like the speeds, my battery takes a considerable hit.
I live in Canada as well. I've only just started using 4G for the past few days (Rogers) and I think I'm going to be sticking with it. Data speeds have improved significantly. I don't seem to have that decrease in voice call quality that someone else mentioned and my battery life is actually not that much worse compared to 3G.
Technically, there is not a network in the US that's adhering to the actual 4G standard. Verizon's LTE may offer slightly better latency, and a better upload speed than T-Mobile, but your wallet will be taking a huge hit, and you'll only have 2GB of data for $110 after taxes and FCC fees. Is LTE really worth more than $100 a month? I don't think so.
I'm using T-Mobile's network and I'm very happy with the speeds. If T-Mobile is prevalent in your area, and you don't travel very often to remote areas, their $30 prepaid plan is definitely worth it. I'm witnessing over 22Mb down on the 42Mbps towers, and I'm averaging roughly 10Mb down everywhere else. I'm about 35 miles from a major urban city, btw.

Saving Battery - LTE

Hi. I was just wondering if it would save more battery to disable LTE because in my country only certain areas have LTE. So would the radio searching for LTE drain life? I read somewhere that because of the integrated radios in the Snapdragon 600 series, there shouldn't be much difference from 3G, H, and LTE. Any thoughts?
Can't say for certain as i haven't got LTE in my area, but it can't hurt, right?
I believe that LTE does use more power in general, so it's probably a good idea anyway unless you really need it.

I have LTE in my area, but I've noticed that if I turn it off the battery life does get better. Now if this is because it isn't actually connected or because it isn't looking, I'm not sure. But let us know!

It's because it isn't connected and actively using the LTE signal. It doesn't make any sense that any phone will be looking for a signal which is disabled.
I have very decent battery performance even when almost all the LTE areas in my city have 1-3 bars most of the time. I woudn't turn it off unless you see a massive improvement, like in one more hour of usage a day or something around that.
I guess there's not much difference with it being on and off. Yesterday mine drained 1 percent per hour of not using the phone in LTE.
Anyone else can contribute with their experience?

Great work. Should be useful to Sprint users.
You can skip the computer part if you install logcat and begin at step 5 after launching.

Wouldn't battery use increase from enabling this? Because it would be constantly scanning for the other 2 frequencies?

True enough, but you need to get the right logcat app, some don't work as well as others. I initially tried aLogCat, but didn't seem to work. CatLog app worked great, however.

Just saying. No one has been able to get a B41 (TDD-LTE 2496-2690) connection with a Nexus 5 and that's with actual maps of Clearwire sites that's been upgraded and knowing where each site is located at. I've personally visited over 24 sites to no avail and know of others that visited many sites as well. Looks to be a much bigger issue than just changing up the LTE Engineering settings and may be network related.
Just got the phone but I'm pretty disappointed with the LTE speeds 1/2mb down, outside it's a bit better. Went downstairs and it disconnects from LTE altogether. Anyone know if it's a radio (hardware) issue with the phone or firmware radio? Some spots of my house won't even catch LTE, whereas my s2 would get wimax.
I've tried spark but it makes my connection more unreliable more pocket loss, but indeed it does seem to make it faster, placebo? I'm in Los Angeles don't know if it's been rolled out. I tried updating prl/profile to no avail. My next choice would be to try the LG 2 in hope of it having a better radio.
GPS is spot on, and wow this thing is fast!
Just a question, but wouldn't prioritizing band 26 make more sense since that is the 800MHz frequency band?

No, band 41 has the most capacity so you would want to connect to that if you are actually in range of it. It will automatically drop you down to the lower frequency bands as you move out of range of the higher frequency bands.

Hello, I tried this on my N% for Sprint today. btw. I live in N. OC, near Los Angeles. If I happen to be in and out of spotty LTE coverage areas. Will these adjustments cause more battery use or or worse performance?
When viewing HD youtube videos, it seems to play smoothly for a while, and then pauses as it the speed is going and up and down or being throttled.
About Band 41
So you means the Band 41 is unopen under default setting?
we need to open it by manual?
You know, the biggest mobile carrier China Mobile's 4G is TDD-LTE, and also use the band 41
But if I use the 4G sim card, it still work in 2G.

I am with uh60james spark seems to offer more throughput and less disconnects.
I drove to Corona from Carson the other day and i was shocked how much coverage sprint has improved on. I wasn't able to stay connected to LTE on my the entirety of my drive but it is impressive how Sprint has extended lte coverage around corona at least on the freeway.
Spark works better for me, less drop offs.
I am in Naperville. Will check this out and see if tri band goes this far out west from chicago.

I haven't heard anything about DFW having Spark anytime soon, so more than likely not. I live in Arlington myself, and would love to see this area Spark-enabled sooner than later.
Enabled this on my n5 a couple weeks ago .... dismal speeds on lte in downtown Los Angeles as usual around 4 down and 2 up.... Yesterday for the first time spark kicked in and I got 44down and 14 up. BUUUUT today its back and slower than ever. around 2 down/1up on LTE

Seems that due to Nexus 5 lacks TD-SCDMA for China Mobile 3G, it is very hard for Nexus 5 auto connect to LTE.
You need *#*#4636#*#*, change mode to "LTE Only" and wait connect to band 41/38 cell and then change it back to "LTE/GSM Auto (PRL)".
After it, you will on LTE until one of following happens: no LTE cell signal; incoming call; make a outgoing call. If fallback to GSM, you will need another round of "LTE Only" settings. Please check some chinese forums, there are plenty of guides.
It seems N5's baseband firmware did not implement some directly GSM to LTE function and do not support China Mobile 3G, so ...

Slow 4g lte

My phone is showing 4G LTE icon with either full bars or close to it, yet my speeds are horrible. Speed test app would show like 0.29 Mbps on average. I've seen this phone reach high speeds like 39 Mbps elsewhere, but around here it's pretty bad. Data speeds would be slow or I get connection time out errors. During less busy times, I might sometimes reach 1-4 Mbps, but that's temporary. Is there something I could do to get some usable speeds? I remember back in tmo gs1 days, I could edit the build.prop with some lines and improved my speeds. I am on a 910T3 rooted phone with a custom rom on a DOK2 modem. Thank you.
They may working on tower close to you. Call tmo tech support and let them know. I remember when similar situation was going in my area, switching to 4g instead lte gave me faster download/upload speeds.
